Just sent an email to KYB about possible options for replacement springs for the stock R-spec shocks. Hopefully this will be another option besides the eibach springs.

It would be nice to know the factory specs for front & rear Spring Rate (lbs/in).

My buddies that have family members that race, take their shocks to several different shops and have them re-valved and/or re-sprung all the time.
Just something to think about.

These are the springs that Walker Evans Racing uses on their shocks, Or you could just get Summit Racing springs that are made by Eibach and save https://www.summitracing.com/search...ings?fr=part-type&autoview=SKU&ibanner=SREPD5

front - https://www.summitracing.com/parts/eib-14002500250
rear - https://www.summitracing.com/parts/eib-14002500225s
Rear Spacer - https://eibach.com/us/c-117-product...race-spring-accessories-coupling-spacers.html

Eibach 1400.250.0250S 14" x 2.5" I.D. Coil-Over Spring
Eibach 1400.250.0225S 14" x 2.5" I.D. Coil Over Spring

It be nice to know what spring rate KYB uses on factory. to compare to the Walker Evans. Eibach also makes the spring cup adapters. Keep up posted on what they say.

Another member has his KYBs at a shop right now getting the spring rate figured out. Once that done will post the info. I figure will be able to do it for half the price of what JBS sells his for and it will be the exact same....lol...

Front only require springs as the spring KYB plate fits.
Rear requires springs and new spring plate as the KYB spring plate will not seat.

Ill be taking my rear shocks apart Sunday to measure the rear spring seat and figure out the Eibach part #

It is significant to just have a shock tune-up to change out the oil, check seals and freshen the nitrogen. You do not even have to re-valve them ($$) if you not riding very aggressively. These are good shocks that have the adjustments needed for most riders. They are a mechanical unit that requires periodic maintenance that gets typically ignored. There is no factory direction on this and shops are somewhat hard to find at a local level without shipping off. My nephew has a racing shock business for quad racers who does this for me, and my four year old units are about to get the treatment. Did it on my Rhino and totally worth it.
